I would suggest you take out the cabinet that is to the right of the stove and use it elsewhere in the house -- perhaps in the bathroom or dining room with a hutch above it. Then, I would suggest you have someone install a lazy susan cabinet in the corner between the sink counter and the stove, meaning you would move the stove down a bit and have a small cabinet/counter top to the right of the stove. I would suggest you have the cabinets refinished in white and then paint the walls a pastel you like. If you would prefer white walls, then add white-painted crown molding and paint the ceiling a light neutral blue, such as Sherwin Williams Niagara Falls Blue. Then, I would suggest you choose a favorite accent color and use this sparingly in accessories like towels, pot holders, small vases or floral arrangements, and a valence above the triple windows. For a genuine 1940s look, you might have white ceramic square tiles with a rectangular red border installed as a back splash behind and above the stove. If you are replacing counter tops, I would suggest a light color such as white with a beige or light grey vein or striation for some sort of pattern. You might be able to find the same color and design in floor tile OR opt for a wood floor as another poster suggested.

Beautiful table. I don't particularly like the metal/cane chairs. Too 'light' in appearance. Do you use the chairs by the window? I think they are too close to the table and they are too big in comparison. Could be the angle of the photos though, may look different in real life. I don't think your ceiling is too low to hang a pendant above the table. How do you change the table position? If you only turn it around, you can still keep it centered under a light. If you move it to the wall it's another story of course. The two paintings above the console should be hung lower and I prefer them on one level. You can add table lamps on the console and a floor lamp in the corner between the windows. If you use the two chairs, I would add a table in between and angle the chairs a bit. I'll see if I can find you other dining chair options.

I found this photo online, perhaps it will help. In this picture the crown molding on the cabinets flow from the kitchen to the adjoining room. Maintaining continuity with the color and some of the trim detail will make the rooms transition nicely. Don't overlook the details like hardware finish, lighting and plumbing fixtures as these elements can also tie the two styles together. I hope this was helpful.

Well you posted this several months ago, but I thought I would make suggestions anyway. Hope you don't mind. In order to stay with or keep in mind the style of the shelves I would first change out the towel rack and TP holder to a chrome, or brushed nickel finish. Or get something that goes with the water faucet on the sink. If you are going to paint the wood around the shower base, paint the window trim and pieces of baseboard that are wood as well. I agree with using a gray color that adalisa, above mentioned. Maybe paint your vanity a darker gray, or even a shade of black, like your shelves to tie it in. That's it for me.
